This is one of my favorite events of the year, and I’d love you to join me! I’m excited to be returning to the stage at the Eudemonia Summit this year to speak on the latest in brain science research. If you’re not familiar, Eudemonia sits at the intersection of performance, philosophy, and science—bringing together ideas that shape how we think about health and human potential. It’s more than a conference; it’s a gathering of people passionate about expanding human health and wellbeing.
This year’s lineup includes an exceptional group of physicians, researchers, and health leaders—individuals who have spent years advancing their fields and are actively shaping what comes next. One of the things I appreciate most about Eudemonia is its openness to diverse perspectives, creating space for meaningful dialogue and a more complete view of complex topics.
Eudemonia takes place November 5–8 in West Palm Beach. If you’re interested in exploring brain health, performance, and the future of wellness, I hope you’ll join me for the conversations, experiences, and community that make this event unique.
